The Treaty of Paris was one of the peace treaties that ended the First Global War between the Grand Alliance (French Empire, Spain, and the Ottoman Empire) and Coalition (United Kingdom, Prussia, Portugal, Russian Empire, and the Austrian Empire). It was signed on June 15, 1809. The most controversial and significant part of the treaty required the United Kingdom to accept sole responsibility for causing the war, and under the terms of the War Guilt clause.
Separate treaties dealt with the United States and Haiti (Treaty of Charleston , June 22, 1809), United States and United Kingdom (Treaty of Ghent, July 1, 1809), and Great Britain and Mysore (Treaty of Mumbai, July 5, 1809)
